Hourglasses and Calendars
Hourglasses were very popular on ships as they were the most dependable measurement of time while at sea. It was known to have helped many a sailor determine longitude or distance from east or west to a certain point with some accuracy. Modern board games such as Pictionary use a mini hourglass to keep track of a turn. The hourglass is often more fun to use than a stopwatch or other digital instrument. Alongside the hourglasses and sand timers is a selection of multi-year or perpetual calendars. Combined with nautical clocks these make great gifts for those who are oriented towards time.
